The following figure shows the reference design of the 6-pin USIM card. Figure 6: Reference Circuit of the 6 Pin USIM Card In order to enhance the reliability and availability of the USIM card in your application, please follow the criteria below in the USIM circuit design:  Keep layout of USIM card as close to the module as possible. Assure the length of the trace as less than 200mm as possible.  Keep USIM card signal away from RF and power supply alignment.  The decouple capacitor of USIM_VDD should be less than 1uF and must be close to USIM connector.  To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away from each other and shield them with surrounding ground.  In order to offer good ESD protection, it is recommended to add TVS such as WILL (http://www.willsemi.com) ESDA6V8AV6. The 22Ω resistors should be added in series between the module and USIM card so as to suppress the EMI spurious transmission and enhance the ESD protection. The 33pF capacitors are used for filtering interference of EGSM900. Please note that the USIM peripheral circuit should be close to the USIM connector.  The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace and sensitive occasion are applied. 10 USIM_DATA IO USIM/SIM data signal. 1.8V/3.0V 12 USIM_CLK DO USIM/SIM clock signal. 1.8V/3.0V 14 USIM_RST DO USIM/SIM reset signal. 1.8V/3.0V

ModuleUSB_ DPUSB_DMGNDMCUDifferential layoutUSB_DPUSB_DMGNDNM_2pFVCC_MCUVCC Figure 8: Reference Circuit of USB Interface To ensure the USB interface design corresponds with the USB 2.0 specification, please comply with the following principles.  It is important to route the USB signal traces as differential pairs with total grounding. The impedance of USB differential trace is 90ohm.  Do not route signal traces under crystals, oscillators, magnetic devices and RF signal traces. It is important to route the USB differential traces in inner-layer with ground shielding, and not only upper and lower layer but also right and left side should be shielded.  If you use the USB connector, you should install the ESD components as close to the USB connector as possible. Pay attention to the influence of junction capacitance of ESD component on USB data lines. Typically, the capacitance value should be less than 2pF (e.g.ESD9L5.0ST5G).

UMTS/HSDPA Module Series UC15 Mini PCIe Hardware Design UC15_Mini_PCIe_Hardware_Design Confidential / Released 24 / 40 There are three preconditions when enabling UC15 Mini PCIe to enter the sleep mode: 1. Execute AT command AT+QSCLK=1 to enable the sleep mode. Refer to document [2]. 2. UART_DTR pin should be kept in high level (pull-up internally). 3. USB interface on Mini PCIe must be connected with your USB interface, and guarantee USB devices are in the suspended state. 3.7. Audio Interface 3.7.1. Digital Audio Interface UC15 Mini PCIe Telematics version provides one Pulse Code Modulation (PCM) digital audio interface, which supports the following modes.  Short sync mode (works as both master and slave)  Long sync mode (works as master only) When module works in the short sync mode, PCM_CLK=2048kHz and PCM_SYNC=8kHz. The data is sampled on the falling edge of the PCM_CLK and transmitted on the rising edge, and the PCM_SYNC falling edge represents the MSB. When module works in the long sync mode, PCM_CLK=128kHz and PCM_SYNC=8kHz. The data is sampled on the falling edge of the PCM_CLK and transmitted on the rising edge, and the PCM_SYNC rising edge represents the MSB. The following figures show timing relationship of these two modes. Figure 9: Short Sync Mode Timing NOTES

AT+QSIDET is to set the side-tone gain level. For more details, please refer to document [2]. The 33pF capacitors and 10pF capacitors are applied for filtering out 850/900/1800/1900MHz RF interference. However, the self-resonant frequency point of capacitor largely depends on the material and production technique. Therefore, you should depend on the capacitor vendor to choose the most suitable capacitor for filtering out GSM850, EGSM900, DCS1800 and PCS1900 separately. In order to decrease radio or other signal interference, RF antenna should be kept away from audio interface and audio alignment. Power alignment and audio alignment should not be parallel, and power alignment should be far away from audio alignment. The differential audio traces should be placed according to the differential signal layout rules. 3.8. Control Signals The following table shows the pin definition of control signals.
